I am reading data from a database that is incompatible with ArcGIS Pro into an ESRI geodatabase using the .Net SDK. The database stores primary keys as GUIDs e.g. {e372ad91-9e24-4054-9454-5bb31657f2db} which is the same format as a GUID field in an ESRI file geodatabase (.gdb).
However, if I try to write these GUIDs to a file geodatabase, I get an exception at the line where I add the GUID field to the row buffer:
| Name | Value | Type |
|---|
| ◢ | $exception | {"A general error when something is wrong with a Field."} | ArcGIS.Core.Data.GeodatabaseFieldException |
Are GUIDs in file geodatabases handled in a special way? I can't seem to write in new ones generated outside of ArcGIS Pro.
Thank you very much in advance.
Here is the basic outline of my code and a mock feature table to illustrate my question:
| FacilityID | Name | OwnType | GUIDField |
|---|
| 1 | Griffith Park | Municipal | {e372ad91-9e24-4054-9454-5bb31657f2db} |
| 2 | London | Municipal | {zyxqad91-7g76-9999-9434-5aa31657f2db} |
| 3 | India | Municipal | {abc1ad91-9e24-8888-1234-5aa12345f2db} |
public async Task CreatingAFeature() {
string message = String.Empty;
bool creationResult = false;
await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
using (Geodatabase geodatabase = new Geodatabase(new Geodatabase(new FileGeodatabaseConnectionPath(new Uri("filePath")));))))
using (FeatureClass featureClass = geodatabase.OpenDataset<FeatureClass>("FeatureClassName"))
{
//declare the callback
EditOperation editOperation = new EditOperation();
editOperation.Callback(context =>
{
FeatureClassDefinition facilitySiteDefinition = featureClass.GetDefinition();
int facilityIdIndex = facilitySiteDefinition.FindField("FACILITYID");
using (RowBuffer rowBuffer = featureClass.CreateRowBuffer())
{
// Fill fields of row buffer
rowBuffer["facilityId"] = 4;
rowBuffer["NAME"] = "Griffith Park";
rowBuffer["OWNTYPE"] = "Municipal";
/* The line that throws the exception.
Commenting out this line makes everything run fine
I generate a new GUID here for the sake of the example.
Trying to write a GUID from the dataset, or writing the GUID
as a string also throws an exception.
*/
rowBuffer["GUIDField"] = Guid.NewGuid(); // The line that throws the exception.
... code continues
